Fabspeed Deluxe Dual Style Tips, Titanium.

The Fabspeed Deluxe Dual Style Exhaust Tips are a premium visual and finishing upgrade designed for the 2014–2016 Porsche 991 GT3 and GT3 RS.

Fits:

• Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
• Porsche 991.1 GT3 RS 4.0L (500 Bhp) 2015-16  

Featuring larger 100mm outlets compared with approximately 88mm factory tips, they give the rear of the GT3 a wider, more aggressive appearance while retaining a factory-style fit.

The tips are designed to bolt directly to the OEM centre muffler and can also be used with compatible aftermarket exhaust systems that accept factory-style exhaust tips.

A lightweight holder plate is used to secure the tips in position while maintaining correct alignment with the rear bumper and exhaust outlet.

What This Product Does:
Exhaust tips form the visible final outlet of the exhaust system.

Their main purpose is to direct exhaust gases away from the rear of the vehicle while providing a finished appearance at the exhaust outlet.

The Fabspeed Deluxe Dual Style Tips are primarily designed to:

• Increase the visual size of the exhaust outlets
• Give the GT3 a more aggressive rear appearance
• Replace damaged or deteriorated factory exhaust tips
• Maintain correct exhaust outlet positioning
• Provide secure attachment to the centre muffler
• Offer a choice of premium finishes
• Work with the factory centre muffler
• Work with compatible aftermarket exhaust systems

These exhaust tips are primarily an appearance and finishing upgrade rather than a significant engine-performance modification.

Symptoms Of Wear Or Failure:
Exhaust tips are exposed continuously to exhaust heat, condensation, road debris and environmental contamination.

Common signs of deterioration include:

• Heavy surface corrosion
• Pitting or staining
• Burnt or permanently discoloured surfaces
• Scratches or cosmetic damage
• Dents from impact
• Cracked welds or mounting points
• Loose mounting hardware
• Rattling from the exhaust-tip assembly
• Tip movement when touched
• Poor alignment within the bumper opening
• One outlet sitting lower or further outward than the other
• Excessive soot build-up
• Damaged carbon-fibre outer sections where fitted
• Peeling or deteriorated surface coatings
• Contact between the tip and surrounding bumper or trim

Some discoloration and soot accumulation are normal on performance exhaust systems and do not necessarily mean the tip requires replacement.

Why Replacement Matters:
In many cases, exhaust-tip replacement is primarily cosmetic. Worn, heavily scratched, corroded or discoloured tips can detract significantly from the appearance of the rear of the vehicle.

However, replacement becomes more important where the tip or mounting system is physically damaged.

A loose or misaligned exhaust tip can:

• Rattle during driving
• Contact the bumper or diffuser
• Damage surrounding trim
• Move excessively during exhaust-system vibration
• Sit incorrectly within the rear valance
• Eventually loosen further or detach

Replacing damaged tips and ensuring the mounting hardware is secure helps restore correct alignment and prevents unnecessary contact with surrounding bodywork.

Fabspeed Deluxe Quad-Style Tips, Carbon Fiber (NON-S / NON-PSE).
The Fabspeed Porsche 991 Carrera Deluxe Quad-Style Tips are a premium exhaust styling upgrade designed for 2012–2016 Porsche 991 Carrera NON-S models without Porsche Sport Exhaust (NON-PSE).

Fits:

• Porsche 991.1 Carrera C2 3.4L (350 Bhp) 2012-16
• Porsche 991.1 Carrera C4 3.4L (350 Bhp) 2012-16  

Designed to replace the standard factory exhaust tips, these quad-style outlets give the rear of the Porsche 991 Carrera a wider, more aggressive appearance while retaining compatibility with the factory OEM mufflers.

Manufactured from high-quality T304 stainless steel, each outlet measures 3.5 inches / 90 mm in diameter.

Unlike a complete exhaust system, these tips primarily provide a visual exhaust upgrade. They do not replace the mufflers or catalytic converters and should not be treated as a significant engine-performance modification.

What This Product Does:
The Fabspeed Deluxe Quad-Style Tips replace the standard exhaust outlets at the rear of the Porsche 991 Carrera.

Their primary function is to provide a larger and more distinctive exhaust outlet design.

The quad-tip arrangement creates the appearance of four exhaust outlets across the rear of the vehicle, giving the Carrera a more purposeful performance-inspired look.

They provide:

• More aggressive rear styling
• Quad-outlet exhaust appearance
• Larger 90 mm outlets
• A premium stainless-steel finish
• Improved visual integration with the rear bumper
• A straightforward alternative to the standard factory tips
• Compatibility with factory NON-PSE mufflers
• Compatibility with Fabspeed exhaust systems

Exhaust Styling Upgrade:

Exhaust tips are one of the most visible components of the exhaust system.

Because they sit directly beneath the rear bumper, changing their size, shape and finish can substantially alter the appearance of the vehicle without replacing the complete exhaust system.

The Fabspeed quad-style arrangement gives the 991 Carrera a broader and more performance-oriented appearance while maintaining a design appropriate for the shape of the factory rear bumper.

Why Upgrading Matters:
These Fabspeed tips are primarily an appearance upgrade rather than a conventional wear replacement or major performance component.

Owners may choose them even when the original tips remain serviceable.

Reasons for upgrading include:

• More aggressive quad-tip styling
• Larger 90 mm exhaust outlets
• Premium T304 stainless-steel construction
• Improved rear-end appearance
• Compatibility with OEM mufflers
• Compatibility with Fabspeed exhaust systems
• Straightforward bolt-on installation

This makes them suitable for owners who want to change the appearance of their Porsche without replacing the complete rear exhaust system.

Fabspeed Long Tube Competition Race Header System.

The Fabspeed Long Tube Competition Race Header System is a motorsport-focused exhaust upgrade developed for the 2014–2016 Porsche 991 GT3, GT3 RS and 911 R.

Fits:

• Porsche 991.1 R 4.0L (500 Bhp) 2016
• Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
• Porsche 991.1 GT3 RS 4.0L (500 Bhp) 2015-16  

Designed specifically for racing, track and closed-course applications, the system replaces the restrictive factory header, catalyst and side-muffler arrangement with a high-flow long-tube exhaust configuration engineered to maximise horsepower, torque and throttle response.

The package combines:

• Long-tube competition race headers
• Burns Stainless high-velocity merge collectors
• Integral side muffler bypass pipes
• Premium Helical exhaust valves
• High-flow T304 stainless-steel construction

The system was developed through CAD modelling, Dynojet testing and track development to improve exhaust flow throughout the engine's operating range.

What This Product Does:
The exhaust headers collect combustion gases as they leave each cylinder and direct them into the remaining exhaust system.

Header length, primary-pipe diameter, collector design and exhaust restriction all influence how efficiently these gases leave the engine.

The Fabspeed Long Tube Competition system is designed to:

• Increase exhaust gas flow
• Reduce exhaust restriction
• Improve exhaust scavenging
• Increase horsepower
• Increase torque
• Improve throttle response
• Strengthen mid-range power delivery
• Improve high-RPM breathing
• Reduce rear exhaust-system weight
• Produce a significantly more aggressive motorsport exhaust note
• Bypass restrictive factory side mufflers
• Provide valved control within the side-muffler bypass arrangement

This system is intended primarily for maximum track performance rather than road-going refinement.

Symptoms Of Wear Or Failure:
Factory GT3 exhaust components are exposed to extreme temperatures, vibration and repeated thermal cycling.

Common symptoms of deteriorating headers, catalysts or side mufflers can include:

• Ticking or tapping from the header area
• Blowing or hissing exhaust leaks
• Black soot around flange connections
• Cracked headers or welds
• Damaged or warped header flanges
• Catalyst rattling
• Reduced high-RPM performance
• Sluggish throttle response
• Excessive exhaust heat
• Metallic rattling from mufflers
• Broken internal muffler components
• Loose exhaust mounting hardware
• Increased exhaust vibration
• Check Engine Light relating to catalyst efficiency
• Sulphur-like smell from a deteriorating catalyst
• Visible heat damage around exhaust joints

Similar symptoms can also result from damaged exhaust gaskets, oxygen sensors or heat shields, so complete diagnosis is recommended before replacing components.

Why Replacement Matters:
A damaged or leaking header can allow extremely hot exhaust gases to escape into the surrounding engine area.

A deteriorating catalyst or internally damaged muffler can also increase exhaust restriction.

Continued use of damaged components may contribute to:

• Reduced engine performance
• Poor throttle response
• Increased exhaust temperatures
• Additional stress on surrounding components
• Exhaust leakage
• Unwanted vibration or rattling
• Further damage to adjoining exhaust components
• Replacing deteriorated parts restores a secure exhaust path.

For a vehicle with serviceable factory components, the Fabspeed system should be regarded primarily as a competition performance, sound and weight-reduction upgrade.

Fabspeed Long Tube Race Headers.

The Fabspeed Long Tube Race Headers are a competition-focused exhaust upgrade developed for naturally aspirated Porsche 911 GT3, GT3 RS and 911 R models of the 991 generation.

Fits:

• Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
• Porsche 991.2 GT3 4.0L (500 Bhp) 2017-19  

Designed for circuit, motorsport and off-road applications, the system replaces the factory catalytic-converter-equipped headers with a carefully developed long-tube header arrangement engineered to improve exhaust scavenging, reduce restriction and maximise the breathing potential of Porsche's high-revving flat-six engine.

Fabspeed developed the system in conjunction with Burns Stainless, using motorsport-derived high-velocity merge collectors and long primary tubes to improve the way exhaust pulses leave each cylinder and combine within the exhaust system.

The headers are manufactured from T321 stainless steel, CNC mandrel bent and hand TIG welded with back-purging. T321 is particularly well suited to high-temperature motorsport exhaust applications because of its excellent resistance to repeated thermal cycling.

Fabspeed's current product listing quotes performance gains of approximately:

+19 HP

+13 lb-ft of torque

These are manufacturer-listed figures from specific testing and should not be regarded as guaranteed gains for every vehicle.

Because the system removes the original catalytic converters, it is specifically intended for closed-course competition and off-road use rather than public-road use.

What This Product Does:
The Long Tube Race Headers replace the original Porsche exhaust manifolds and catalytic-converter assemblies with a freer-flowing competition header system.

They are designed to:

• Improve exhaust gas evacuation from each cylinder.
• Reduce exhaust restriction.
• Improve exhaust pulse scavenging.
• Support increased horsepower and torque.
• Improve throttle response.
• Enhance high-RPM breathing.
• Complement the high-revving character of the GT3 engine.
• Produce a significantly more aggressive exhaust note.
• Reduce catalyst-related exhaust restriction.
• Support additional competition engine and exhaust modifications.

Symptoms Of Wear Or Failure:
Race headers are exposed to severe temperature and vibration.

Possible symptoms of deterioration include:

• Ticking noises from the exhaust.
• Blowing noises during acceleration.
• Visible exhaust leaks.
• Soot around welds or flanges.
• Cracked primary tubes.
• Cracked welds.
• Damaged collectors.
• Loose slip joints.
• Increased exhaust smell.
• Metallic rattling.
• Exhaust vibration.
• Reduced performance.
• Exhaust noise changing unexpectedly.

Why Replacement Matters:
Replacing cracked or damaged headers helps restore:

• Correct exhaust sealing.
• Intended exhaust scavenging.
• Smooth exhaust flow.
• Proper collector operation.
• Safe containment of hot exhaust gases.
• Structural integrity.
• Consistent engine performance.

For track-driven cars, header condition should be checked regularly because operating temperatures and mechanical loads can be considerably greater than during normal road driving.

Fabspeed RACE Valved Supersport X-Pipe Exhaust System.

The Fabspeed Porsche 991 Turbo / Turbo S Valved Supersport X-Pipe Exhaust System is a high-performance exhaust upgrade designed to deliver enhanced exhaust sound, improved gas flow and driver-controlled exhaust volume for the Porsche 911 Turbo and Turbo S (991.1), manufactured between 2013 and 2016.

Fits:

• Porsche 991.1 Turbo 3.8L (520 Bhp) 2014-16
• Porsche 991.1 Turbo S 3.8L (560 Bhp) 2014-16  

The standard Porsche 991 Turbo exhaust system is engineered to balance performance, emissions and noise regulations. Although effective for everyday driving, its factory mufflers and catalytic converter arrangement can restrict exhaust sound and reduce the audible character of the turbocharged flat-six engine.

Fabspeed developed the Valved Supersport X-Pipe Exhaust System to provide a more engaging exhaust experience while retaining the flexibility of adjustable sound control.

At the heart of the system is a specially engineered 2.75-inch (70 mm) quad-resonated X-pipe, designed to balance exhaust flow and sound characteristics.

With the exhaust valves closed, gases are directed through the resonated X-pipe, producing a smoother, more controlled exhaust note suitable for lower-noise driving.

When the valves are opened, exhaust gases bypass the resonated X-pipe section, creating a more direct flow path and producing a substantially louder, more aggressive exhaust sound.

This dual-mode configuration allows the driver to enjoy two distinct exhaust characteristics from one system.

Manufactured from 14–16 gauge T304L stainless steel, the exhaust uses CNC mandrel-bent tubing to maintain consistent internal pipe diameter and smooth gas flow.

The system incorporates high-quality Helical vacuum-operated exhaust valves, engineered to withstand the high temperatures and demanding operating conditions associated with turbocharged performance engines.

Available with either high-flow sports catalytic converters or race-only catalytic converter bypass pipes, the system can be configured for different performance requirements and intended applications.

The exhaust is completed with Fabspeed's deluxe quad-style exhaust tips, available in a choice of finishes to complement the Porsche 991 Turbo's rear styling.

Designed as a bolt-on replacement, the system can be installed without cutting or welding, making it a substantial exhaust upgrade for enthusiasts seeking improved sound, performance potential and premium construction.

What This Product Does:
The Fabspeed Valved Supersport X-Pipe replaces the corresponding factory exhaust components with a freer-flowing performance exhaust arrangement.

Its main functions include:

• Improves Exhaust Gas Flow: Uses a performance-oriented pipe layout to reduce unnecessary restrictions within the exhaust system.
• Provides Driver-Controlled Exhaust Sound: Allows switching between two distinct sound characteristics.
• Creates a Refined Closed-Valve Mode: Directs exhaust gases through the quad-resonated X-pipe for a smoother, more subdued exhaust note.
• Delivers an Aggressive Open-Valve Mode: Bypasses the resonated section to produce a louder, more direct exhaust sound.
• Enhances Turbocharged Flat-Six Character: Makes the distinctive exhaust note of the Porsche 3.8L twin-turbocharged engine more prominent.
• Supports Performance Optimisation: Provides an exhaust configuration designed to improve flow and potentially enhance engine response.
• Reduces Exhaust System Weight: Fabspeed lists an approximate 5 lb weight reduction compared with the corresponding factory arrangement.
• Uses High-Flow Stainless Steel Pipework: Mandrel-bent tubing helps maintain consistent exhaust flow through pipe bends.
• Provides Durable Valve Operation: Uses Helical vacuum-actuated valves designed for high-temperature service.
• Enhances Rear Styling: Includes deluxe quad-style exhaust tips.
• Supports Different Vehicle Configurations: Offers valve-control options for vehicles with or without factory Porsche Sport Exhaust.
• Maintains Bolt-On Installation: Designed to fit the corresponding Porsche 991 Turbo application without cutting or welding.

Symptoms Of Wear Or Failure:
The Fabspeed Valved Supersport X-Pipe is primarily a performance upgrade rather than a component that must be replaced at a fixed service interval.

However, deterioration of the original exhaust system or faults within an existing valved exhaust assembly may make replacement or repair necessary.

• Hissing, ticking or blowing noises.
• Increased exhaust volume from an unexpected location.
• Soot deposits around exhaust joints.
• Exhaust fumes around the rear of the vehicle.
• Increased noise during acceleration.
• Visible rust or deterioration.
• Weak or damaged welds.
• Cracked mounting points.
• Perforated pipework.
• Exhaust sections becoming loose or insecure.
• Exhaust sound remaining unchanged when switching modes.
• One exhaust valve operating while the other remains stationary.
• A valve stuck open, causing consistently high exhaust volume.
• A valve stuck closed, preventing the louder operating mode.
• Unusual metallic rattling around the valve assemblies.
• Irregular valve movement.

Why Replacement / Upgrading Matters:
Upgrading to the Fabspeed Valved Supersport X-Pipe can improve the driving experience by combining performance-oriented exhaust flow with adjustable sound control.

• Two Exhaust Sounds in One System: Switches between a more refined resonated mode and a louder performance mode.
• Enhanced Exhaust Character: Brings out the distinctive sound of the Porsche 991 Turbo's twin-turbocharged flat-six engine.
• Improved Exhaust Flow: Uses larger performance-oriented pipework and an optimised flow path.
• Potential Performance Gains: Designed to support improved power delivery and throttle response, depending on vehicle configuration.
• High-Quality Construction: T304L stainless steel provides excellent resistance to corrosion and heat-related deterioration.
• Premium Helical Exhaust Valves: Provides a durable valve arrangement engineered for demanding operating conditions.
• CNC Mandrel-Bent Tubing: Maintains a consistent internal diameter through bends to support smooth gas flow.
• Reduced Exhaust Weight: Offers a lighter configuration than the corresponding original exhaust arrangement.
• Customisable Appearance: Deluxe quad-style tips provide a choice of finishes.
